Do a Barrel Roll — Power Evaluation
Final Score: 50 ± 8 · Confidence: Medium
- Intrinsic: 50 · Deck: 50 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Material body
Why it scores here
Do a Barrel Roll is a conditional Trap that negates a Spell, Trap or monster effect and destroys the source, but only if you can Tribute Mecha Phantom Beast Tokens you control. Its value therefore depends on token generation being live, which the evidence does not show directly. Its effect-interaction score is the main driver, and its use is confined to the Mecha Phantom Beast shell (4 of 4 sampled decks, all with core MPB partners). High deck presence confirms it is a played piece, not that it is strong in isolation, so the score stays near the middle.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Live only when MPB Tokens are on the field, which is inferred from text and the MPB partner set; no starter or searched data is supplied (inferred). |
| Combo & Conversion | 30 | No combo boards were supplied, so conversion is text-only: it trades tokens for a negation and does not build a board by itself (inferred). |
| Resource Economy | 50 | Tributing tokens and destroying the activation source is roughly even card-for-token exchange, with no draw, search or recursion (inferred). |
| Effect & Interaction | 65 | Negates Spell, Trap and monster effect activations, which is broad coverage, but gated on a token cost and a Trap's set-zone exposure (verified text, inferred reach). |
| Material Utility | 5 | Trap card, not a monster, so it has no material value and cannot be used as material (verified). |
| Resilience & Flexibility | 35 | Set Trap vulnerable to backrow removal and dependent on tokens staying on the field; only partial redundancy across two MPB archetype homes (inferred). |
| Deck-Building Efficiency | 45 | Runs at an average of 2.25 copies across 4 decks with no garnet or lock; the archetype restriction limits splashability (observed deck data, inferred restriction). |
Calculation
Weight profile: Removal / Negation primary role profile, single role (no secondary blend). Intrinsic ≈ 50, Deck ≈ 50, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Broad negation scope across Spell, Trap and monster effect activations
- Consistently included in MPB homes (4 of 4 sampled decks, 3 copies typical)
- Destroys the activation source in addition to negating it
Weaknesses
- Requires Mecha Phantom Beast Tokens on the field to tribute, so it is dead without them
- Confined to the Mecha Phantom Beast archetype
- Set Trap exposed to backrow removal
Counters / choke points
- Backrow removal or Trap destruction before activation
- Opponent Spells and monsters that avoid activation, or that do not need to be negated, can play around it when no tokens are present
Best use
Conditional negation / backrow interaction. Decks: Mecha Phantom Beast token decks. Suggested copies: 3.
Evidence & gaps
- Verified: Card text: negates a Spell, Trap or monster effect activation and destroys it, conditional on tributing MPB Tokens; Card type: Trap, so it cannot be used as material; 4 of 4 sampled decks run it in main deck, all in MPB archetypes
- Observed: Average 2.25 copies per deck, max 3; Core MPB partners co-occur in 100% of sampled decks
- Inferred: Reliable access depends on token generation, which is not evidenced in the pack; Backrow exposure and token dependence reduce resilience
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, so 3 copies (unlimited) is assumed no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only no legal copies data for any format token-generation cards and their availability are not in the evidence pack
